Intestinal ischemia-reperfusion injury (IIRI) is common in a variety of critical diseases and acute stress, and acupuncture is a promising treatment for IIRI. The aim of this study is to explore the mechanism of electroacupuncture (EA) at Zusanli (ST36) in improving IIRI from the perspective of the cholinergic anti-inflammatory pathway (CAP) and miRNA 124.

The movement of intestinal smooth muscle is regulated by the external autonomic nervous system (ANS) and its internal enteric nervous system (ENS). Previous studies have shown that acupuncture has a bidirectional regulating effect on intestinal motility through the sympathetic and vagal ANSs. ENS can independently regulate the sensory, secretory, and motor functions of the intestine. The interstitial cells of Cajal (ICC), the pacemaker cells in ENS, play a key role in maintaining gastrointestinal motility. However, studies on the role and mechanism of ICC in the regulation of intestinal function by acupuncture are still unclear.

The American Neurogastroenterology and Motility Society Gastroparesis Cardinal Symptom Index-Daily Diary (ANMS GCSI-DD) is a patient-reported outcome (PRO) instrument for gastroparesis. This study evaluated the psychometric properties of the ANMS GCSI-DD and determined a meaningful change threshold using the data from a phase 2b trial in adults with moderate-to-severe idiopathic or diabetic gastroparesis (DG).

Diabetic gastroenteropathy can cause significant diagnostic challenges. Still, it remains unknown if measures of extraintestinal autonomic function reflect diabetic gastroenteropathy. We aimed to assess the associations between (1) gastrointestinal symptoms and motility measures and (2) gastrointestinal symptoms/motility measures and extraintestinal autonomic markers.

Gastro-esophageal reflux disease (GERD) is the most common cause for noncardiac chest pain (NCCP), with an estimated prevalence rate ranging between 30% and 60%. Heartburn and NCCP may share common mechanisms.

Cyclic vomiting syndrome is a chronic disorder of gut-brain interaction that is present in both adults and children. It is characterized by severe nausea, vomiting, abdominal pain, and several non-GI symptoms. It is also associated with several comorbid conditions such as anxiety and depression, which affect overall health care outcomes.

The knowledge and proficiency of primary care practitioners (PCPs) in diagnosing and managing irritable bowel syndrome (IBS) remain generally low and variable internationally. This variability is partly due to a lack of familiarity with the Rome Foundation diagnostic criteria and treatment guidelines for this condition.

The aims of this study were to confirm the non-inferiority of tegoprazan to lansoprazole up to week 4 in patients with erosive esophagitis (EE) and to evaluate its effectiveness in rapid mucosal healing and symptom relief at week 2.

There is a large unmet need for alternative, non-invasive, and accurate diagnosis of small intestinal bacterial overgrowth (SIBO). The smart capsule bacterial detection system (SCBDS) device contains a targeted sampling technology and an onboard SCBDS assay to detect metabolically active bacteria in the small intestine. Here, we evaluated the agreement of SCBDS assay with duodenal aspiration/culture ex vivo in a multicenter clinical study.

Although different gastric shapes are encountered in gastric emptying scintigraphy (GES), it is not known whether gastric shape is related to gastric emptying (GE) or symptoms.

Functional dyspepsia (FD) is a multifactorial disorder as its development may be based on several different pathophysiological mechanisms. Interaction of gut microbiome with the host has been proposed as a potential mechanism involved in the disease's pathogenesis.

Patients' report of bowel movement consistency is unreliable. We demonstrate the feasibility of long-term automated stool image data collection using a novel Smart Toilet and evaluate a deterministic computer-vision analytic approach to assess stool form according to the Bristol Stool Form Scale (BSFS).

A high prevalence of disorders of gut-brain interaction (DGBI) exist in patients with hypermobile Ehlers-Danlos Syndrome (hEDS) and hypermobility spectrum disorders (HSD). However, it is unknown if clusters of hEDS/HSD patients exist which overlap with different DGBIs and whether this overlap influences presence of comorbidities and quality of life. We aimed to study these knowledge gaps.

Functional diarrhea (FDr) is a common disorder in toddlers and adults. In children, the Rome criteria define FDr as a disorder of children younger than 5 years old exclusively. However, in clinical practice, school-aged children and adolescents sometimes consult for symptoms that mimic the diagnosis of FDr. We conducted a study aimed at assessing the prevalence of FDr in school-aged children and adolescents.

Internationally adopted Chicago Classification (CC) criteria based on adult normative data have been used to diagnose children with esophageal motility disorders undergoing high-resolution esophageal manometry (HREM). The aim of this study was to compare HREM parameters of children without dysphagia and children with dysphagia and normal findings according to CC.

Dumping syndrome is a complex of gastrointestinal symptoms originally studied in peptic ulcer surgery patients. At present, it is most prevalent in patients who underwent bariatric, upper gastrointestinal cancer or anti-reflux surgery. The symptom pattern comprises early and late dumping symptoms. Several management options have been reported including nutritional, pharmacological and surgical approaches.

Postoperative ileus (POI) is a condition marked by a temporary suppression of gastrointestinal motility following abdominal surgery. The mechanism of POI encompasses various factors and is characterized by two phases: the early neurogenic phase involving both adrenergic and non-adrenergic neural pathways; the later immune-mediated phase is characterized by a sterile inflammatory response that lasts several days. Activation of muscularis macrophages triggers a sterile inflammatory process that results in dysfunction of the enteric nervous system (ENS) and a reversible inhibition of gastrointestinal motility.
